Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Cam Upgrade

When I spoke to Stuart E from Krazy Horse at RFTH 2016 he suggested that these are not necessary unless you go even further with tuning and start to look at the 128cu.in barrels etc. This was reiterated by their tech Dan when visiting their dyno last autumn. I don't doubt feedback that suggests smoother running, but they are probably not cheap and I'm not sure I want to go further on my car.....

Having said that, I am easily swayed if any more of you report smoother high-rev running and other tangible benefits!

Thanks for the insight's again nippymog. nothing beat's experience......
Come on Phil its only money and time :laugh2
I think they work out at about £400 ish...

I will dig out the invoice later ( making tea ) , but I am sure I paid way less than £400 - bear with as they say

I stand corrected , £304 including the vat form Matts.

I still think its worth the money , especially when compared to some of the Morgan upgrades I have taken.
I am not bitter

Is the engine still "zero interference" with the increased lift? I.e. when the cam belt breaks, can a valve hit a piston?

Roller rockers in themselves are non interference - its when you go to the high lift cams ( which I think are part of the stage 3 Morgan kit ) you potentially get interference between valves and pistons.
I am sure this is all detailed on the S&S web site , or was a couple of years ago

Yes, agreed. The OP mentioned the rollers he chose increased lift, i.e. had an increased ratio over stock (likely 1.60 vs 1.50 which is typical). I was wondering if the increased lift afforded by these particular rockers caused an interference issue.

Anyone have an idea what stud puller/installer I need to use?
